Run arbitrary JavaScript or PogoScript on a server

censeo

Run arbitrary JavaScript or PogoScript on a server.

Please use this responsibly.

Preferable only in test code

Insructions

First of all you need to start up the server specifying a port number to use. If you are using karma you may want to put this in your karma.conf.js file.

require('censeo').server.listen(3001)

or if you already have an http server

require('censeo').server(http)

Next you want to create a client:

client  = require('censeo').client(3001)

where 3001 is the port censeo is running on

Then in your test (you should only use this for tests!).

client
  .run(function() {
    return 1 + 1;
  }).then(function(result){
    expect(result).to.equal(2)
  })

or

client
  .run(function() {
      var fs = require("fs");
      return new Promise(function(success){
        fs.readdir(process.cwd(), success);
      });
  }).then(function(result) {
      expect(result).to.include("node_modules");
  });

Where censeo can come in really handy is if you need to spool up a webserver to test against. To do this we use runTask which lets you start a task and stop it at a later point:

client
  .runTask(function() {
    var http, app, server;
    http = require("http");
    app = http.createServer(function(req, res) {
        var headers;
        headers = {
            "Content-Type": "text/plain",
            Connection: "Close",
            "Access-Control-Allow-Headers": "accept, x-requested-with, content-type",
            "Access-Control-Allow-Methods": "GET, OPTIONS",
            "Access-Control-Allow-Origin": req.headers.origin
        };
        if (req.method === "OPTIONS") {
            res.writeHead(204, headers);
            return res.end("OK");
        } else {
            res.writeHead(200, headers);
            return res.end("ALIVE");
        }
    });
    server = app.listen(8555);
    console.log("listening on 8555");
    return {
        stop: function(done) {
            var self = this;
            return server.close(done);
        }
    };
}).then(function(task){
  // make some http requests to the server
  // then stop the server
  task.stop(function(){
    console.log('stopped')
  })
})

PogoScript

PogoScript makes using censeo even better:

result = client.run! @{1+1}
expect(result).to.equal(2)

or to run a web server

task = client.runTask!()
  http    = require 'http'
  app = http.createServer @(req, res)
    headers = {
      'Content-Type'                  = 'text/plain'
      'Connection'                    = 'Close'
      'Access-Control-Allow-Headers'  = 'accept, x-requested-with, content-type'
      'Access-Control-Allow-Methods'  = 'GET, OPTIONS'
      'Access-Control-Allow-Origin'   = req.headers.origin
    }
    if (req.method == 'OPTIONS')
      res.writeHead(204, headers)
      res.end('OK')
    else
      res.writeHead(200, headers)
      res.end('ALIVE')
 
  server  = app.listen(8555)
  console.log "listening on 8555"
  {
    stop(done)=
      server.close(done)
  }
 
server url = 'http://localhost:8555'
 
response = request!({url = server url})
expect(response).to.equal('ALIVE')
 
task.stop!()
